3.1.4 CONNECTING RPI TO COMPUTER AND
TRANSCEIVER
RPI Information
The RPI provides the required interface between
the computer and transceiver. It converts the RS-232
logic levels from the computer to the 5V logic levels
required by the transceiver microprocessor and vice
versa.
The current RPI available for programming trans-
ceivers of this type is Part No. 023-9800-000. Earlier
RPI’s, such as 023-9750-000 and 023-5810-000 can
also be used. However, the -9800- RPI is the only one
that has the speaker and microphone audio jacks
required to perform the alignment described in Section
6. In addition, it is the only RPI that can be used to
Flash program the transceiver to update the operating
software.
Cable Information
The cables from the RPI to the computer and
transceiver are not included with the RPI. The -9800-
RPI has a female DB9 connector for the computer
connection. Since most computer serial ports have a
male DB9 or DB25 connector, a male DB9 to female
DB9 or DB25 is usually required. This is a standard
cable available at most computer supply stores. A suit-
able cable is also listed in Table 1-1.
The cable from the RPI to the transceiver
connects from the RPI to the accessory connector of
the transceiver. A schematic diagram of this cable is
shown in Figure 3-2. The -122 version of this cable
can also be used because the extra wire connected to
pin 8 is not required with this radio.
